<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p>The OpenSSL <strong>crypto</strong> library implements a wide range of cryptographic
|
|
algorithms used in various Internet standards. The services provided
|
|
by this library are used by the OpenSSL implementations of SSL, TLS
|
|
and S/MIME, and they have also been used to implement SSH, OpenPGP, and
|
|
other cryptographic standards.</p>
|
|
<p><strong>libcrypto</strong> consists of a number of sub-libraries that implement the
|
|
individual algorithms.</p>
|
|
<p>The functionality includes symmetric encryption, public key
|
|
cryptography and key agreement, certificate handling, cryptographic
|
|
hash functions, cryptographic pseudo-random number generator, and
|
|
various utilities.</p>

|
|
<p>Some of the newer functions follow a naming convention using the numbers
|
|
<strong>0</strong> and <strong>1</strong>. For example the functions:</p>
|
|
<pre>
|
|
int X509_CRL_add0_revoked(X509_CRL *crl, X509_REVOKED *rev);
|
|
int X509_add1_trust_object(X509 *x, const ASN1_OBJECT *obj);</pre>
|
|
<p>The <strong>0</strong> version uses the supplied structure pointer directly
|
|
in the parent and it will be freed up when the parent is freed.
|
|
In the above example <strong>crl</strong> would be freed but <strong>rev</strong> would not.</p>
|
|
<p>The <strong>1</strong> function uses a copy of the supplied structure pointer
|
|
(or in some cases increases its link count) in the parent and
|
|
so both (<strong>x</strong> and <strong>obj</strong> above) should be freed up.</p>
